With the invention of ride-sharing and ride-hailing apps, the number of drunk drivers has actually decreased in most cities. This is a form of transportation that is incredibly popular especially with the younger generation. This could mean that when going out, teenagers are less likely to drive, thus making the argument about reducing drunk driving an invalid point. Though ridesharing does seem to increase the amount of binge drinking that occurs in a night, as no one feels that they have a need to stay responsible enough to drive themselves home.
The United Kingdom has a drinking age of 18, yet alcohol only accounts for approximately 16 percent of fatal road deaths, wherein the United States accounts for about 31 percent.
This proves there is no correlation between the legal drinking age and drunk driving accidents so it is an invalid argument. Drinking and driving depend on the responsibility of the driver, not their age.
